[PATCH] sim: ppc: inline the sim-packages option

[Mike Frysinger <vapier@gentoo.org>]

This has only ever had a single option that's enabled by default.
The objects it adds are pretty small and don't add overhead at
runtime if it isn't used, so just enable it all the time to make
the build code simpler.
